Short summary
Refined source apportionment is urgently needed but hard to achieve due to a lack of specific biomarkers. Recently, Fourier transform ion cyclotron resonance mass spectrometry has been used to analyse the probable chemical structure of polar organic matter emitted from off-road engines. We found more condensed aromatic rings in S-containing compounds for HFO-fueled vessels, while more abundant aliphatic chains were observed in emissions from diesel equipment.
